Polly the parrot has 60 crackers. A mouse stole 45 crackers. Polly wants revenge, so for every five crackers the mouse stole, he is going to bake a pie to throw at the mouse. How many pies must Polly the Parrot bake?

The mouse stole 45 crackers / 5 crackers per pie = <<45/5=9>>9 pies. Answer: \boxed{9}.

so the parrot has to bake nine pies?

Yes, that's correct. Polly the parrot needs to bake nine pies to throw at the mouse as revenge for stealing the crackers.
